</blockquote><h4><a name = "tag_000_010_137">&nbsp;</a>SYNOPSIS</h4><blockquote>

</blockquote><h4><a name = "tag_000_010_138">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>towlower()</i>
function has as a domain a type
<b>wint_t</b>,
the value of which must be a character representable as a
<b>wchar_t</b>,
and must be a wide-character code corresponding to a valid character in the
current locale or the value of WEOF.
If the argument has any other value, the behaviour is undefined.
If the argument of
<i>towlower()</i>
represents an upper-case wide-character code,
and there exists a corresponding lower-case wide-character code
(as defined by character type information in the program locale
category LC_CTYPE), the result is the corresponding
lower-case wide-character code.
All other arguments in the domain are returned unchanged.
</blockquote><h4><a name = "tag_000_010_139">&nbsp;</a>RETURN VALUE</h4><blockquote>
On successful completion,
<i>towlower()</i>
returns the lower-case letter corresponding to the argument passed; otherwise
it returns the argument unchanged.
